When the Ukrainian president was replaced by a US-selected administration, in an entirely unconstitutional takeover, politicians such as William Hague brazenly misled parliament about the legality of what had taken place: the imposition of a pro-western government on Russia’s most neuralgic and politically divided neighbour…

The reality is that, after two decades of eastward Nato expansion, this crisis was triggered by the west’s attempt to pull Ukraine decisively into its orbit and defence structure, via an explicitly anti-Moscow EU association agreement. Its rejection led to the Maidan protests and the installation of an anti-Russian administration – rejected by half the country – that went on to sign the EU and International Monetary Fund agreements regardless.

No Russian government could have acquiesced in such a threat from territory that was at the heart of both Russia and the Soviet Union. Putin’s absorption of Crimea and support for the rebellion in eastern Ukraine is clearly defensive, and the red line now drawn: the east of Ukraine, at least, is not going to be swallowed up by Nato or the EU.
